ASTM F1335-98

1.1 This specification covers pressure-rated composite pipe for the transport of hot or cold liquids, beverages, or gases that are compatible with the composite pipe.

1.2 Composite pipe is produced using a performed butt welded aluminum pipe as the core, with an extruded inside layer of crosslinked polyethylene (PEX) or polyethylene (PE). An adhesive layer is used to bond the inside layer to the wall of the aluminum pipe. An outer layer of polyethylene (PE) and an adhesive layer are extruded to the outer wall of the aluminum pipe.

1.3 Composite pipe is produced in four configurations and referenced in Fig. 1, as Classes 1, 2, 3, and 4 composite pipe.

1.4 The following precautionary caveat pertains only to the test method portion of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.5 The values stated in acceptable SI units are to be regarded as the standard. The values given in parentheses are provided for information only. The values stated in each system are not exact equivalents, therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
